Example 19 with AbstractFileSystem

use of org.apache.hadoop.fs.AbstractFileSystem in project hadoop by apache.

the class ViewFs method listStatus.

@Override
public FileStatus[] listStatus(final Path f) throws AccessControlException, FileNotFoundException, UnresolvedLinkException, IOException {
    InodeTree.ResolveResult<AbstractFileSystem> res = fsState.resolve(getUriPath(f), true);
    FileStatus[] statusLst = res.targetFileSystem.listStatus(res.remainingPath);

        // {@link #getFileStatus }
        ChRootedFs targetFs;
        targetFs = (ChRootedFs) res.targetFileSystem;
        int i = 0;

            String suffix = targetFs.stripOutRoot(status.getPath());
            statusLst[i++] = new ViewFsFileStatus(status, this.makeQualified(suffix.length() == 0 ? f : new Path(res.resolvedPath, suffix)));
        }
    }
    return statusLst;
}

Example 20 with AbstractFileSystem

use of org.apache.hadoop.fs.AbstractFileSystem in project hadoop by apache.

the class ViewFs method getFileStatus.

@Override
public FileStatus getFileStatus(final Path f) throws AccessControlException, FileNotFoundException, UnresolvedLinkException, IOException {
    InodeTree.ResolveResult<AbstractFileSystem> res = fsState.resolve(getUriPath(f), true);
    //  FileStatus#getPath is a fully qualified path relative to the root of 
    // target file system.
    // We need to change it to viewfs URI - relative to root of mount table.
    // The implementors of RawLocalFileSystem were trying to be very smart.
    // They implement FileStatus#getOwener lazily -- the object
    // returned is really a RawLocalFileSystem that expect the
    // FileStatus#getPath to be unchanged so that it can get owner when needed.
    // Hence we need to interpose a new ViewFsFileStatus that works around.
    FileStatus status = res.targetFileSystem.getFileStatus(res.remainingPath);
    return new ViewFsFileStatus(status, this.makeQualified(f));
